Create simple TODO app AngularJS with bootstrap and Spring MVC

In this postwe will show how to create simple TODO application which consists of two main parts.
1. AngularJS GUI client
2. Spring MVC war file as backend for this application

Firstly, we will consider GUI client build on AndroidJS framework.
In Front-end we consider two views and two controllers. First view and controller is for manipulating with login logic and second for showing and retrieving data from server (our backend).
We will use bootstrap framework as our base style, because we want to create responsive design with idea „mobile-first“. Keep in mind that we are not focusing on great design.
So create index and enter page in our TODO app:

Back-end is built on Spring MVC and provides REST API for adding, updating and getting data. We should use any DBMS but for simplicity we will consider only memory-based database.
We need to create two RestControllers for controlling http request from client.
